Abstract:

The paper presents an automatic flue-cured tobacco experimental system based on ARM7 series microcontroller LPC2148.The system uses self-designed digital psychrometer to capture temperature and humidity information,based on which the microcontroller controls the power of heater and ventilation opening to control the temperature and humidity of the system.Meanwhile,temperature and humidity information can be displayed and set on LCD screen and stored in SD card for data analysis.
